3 Claims.

This invention relates to a mounting for closures, such as windows, doors, and the like, and has as its primary object the provision of a support for vertical closures of the type which 5 are advanced edgewise in and out of their closing position.

Another object is to provide a closure mounting of the above character in which the use of tracks and guide ways is obviated.

Another object is to provide a hanger for dependent closures embodying an arrangement of links adapted to permit horizontal rectilinear movement of the closure embodying a construction whereby a balance is maintained throughout the length of movement of the closure and whereby the latter will normally remain at rest in any position throughout the length of its path of travel.

Another object is to provide a closure and a mounting therefor which is especially applicable for use in a confined and limited space.

With the foregoing objects in view, together with such other objects and advantages as may subsequently appear, the invention resides in the parts and in the combination, construction and arrangement of parts hereinafter described and claimed, and illustrated by way of example in the accompanying drawing, in which:

Fig. 1 is a view in front elevation of the closure mounting showing it in its normal position:

Fig. 2 is a view in front elevation of the closure mounting showing it as disposed with the closure in a partly open position:

Fig. 3 is a detail in horizontal section taken on the line 33 of Fig. 2:

Fig. 4 is a View in end elevation as seen in the direction of the arrow 4 in Fig. 1;

Fig. 5 is a view in end elevation as seen in the direction of the arrow 5 in Fig. 1:

Fig. 6 is a detail in horizontal section taken on the line 6-5 of Fig. 1.

Referring to the drawing more specifically A indicates a supporting frame which may be of any suitable construction and which is here 45 shown as comprising an overhead horizontally extending beam 8 supported on spaced uprights 9 and i8 which latter form the vertical side frame members of an opening B. A depending closure is designed to be moved edgewise to efiect opening or closing of the opening B, and which closure is suspended from a mounting D embodying the present invention. As here shown the mounting D includes a horizontally extending metallic bar H which is rigidly secured to a side face of the beam 8 as by bolts I2 and I3 and to which bar is secured by pivots I 3 and I5 a pair of upwardly extending links It and I! the upper ends of which are connected by pivot pins I8 and L9 to a pair of horizontal tie bars 29.

The distance between the centers of the pivots 5 M and i8 of the link H5 corresponds to the distance between the centers of the pivots l5 and IQ of the link l1, and the distance between the centers of the pivots l4 and i5 on the bar ll corresponds to the distance between the centers of l the pivots I8 and I9 on the bars 23 whereby on moving the links it and I! on the pivots M and i5 the links will be maintained in parallel relation with each other, and likewise the bars 20 will be maintained in parallel relation with the fixed bar H.

In carrying out the present invention a toothed segment 2! is provided in the connection between the link I7 and the bars 2!) the segment being disposed concentric with the axis of the pivot I9 and rigidly afiixed to the link ll so as to move with the latter relative to the bars 29 on rocking the link ii. The teeth of the segment 2| are presented toward the ends of the bars 20 which protrude past the upper end of the link ll and intermesh with a companion toothed segment 22 carried by a pivot 23 on the bars 20, and connecting with the segment 22 is a link 24 which extends downwardly and is connected by a pivot 25 to one end of a horizontal bar 26 the other end of which is connected by a pivot 21 to an upwardly extending link 28 connecting with the pivot pin Id at the upper end of the link I6.

The distance between the centers of the pivots 23 and 25 corresponds to the distance between the centers of the pivots 2'! and E8 of the link 28, and likewise to the centers of the pivots at the ends of the links it and H. The distance between the centers of the pivots 25 and 2'! at the ends of the bar 26 corresponds to the distance between the centers of the pivots l8 and 23 on the bars 20, and which distances exceed that of the distances between the pivots M and I5 on the fixed bar I! and also of the pivots I 8 and I 9 on the movable bar 20.

On rocking movement being imparted to the links, which manifestly will swing collectively on movement being imparted to either one or more of the links, the bars 251 and 26 will be maintained in parallel relation with the bar 26 moving 50 on a rectangular path of travel while the bar 20 will move with a combined horizontal and vertical motion.

The closure C is carried by the bar 26 to depend therefrom by hangers 29 and 30 connected 55 to the upper end portion of the closure C and attached to the bar 26 adjacent the ends of the latter.

The mounting D is arranged in such position relative to the opening B that when the links l6, H, 24 and 28 extend vertically the closure C will be positioned to cover the opening B as particularly shown in Fig. 1.

It will now be seen that the links l6 and I! are pivotally carried at their lower ends by the support A and with the tie bar 20 connecting the upper ends thereof constitute the elements of one straight line motion device, while the links 24 and 28 carrying the closure C constitute the elements of another straight line motion device which is supported and carried by the first named straight line motion device, and that the toothed segments 2| and 22 serve as a means for counteracting the movement of one of the straight line motion devices relative to the other.

It will be understood that while the links l6 and I! are shown as pivoted to the bar H they may obviously be connected directly to the support A, and likewise that the lower ends of the links 24 and 28 may be pivotally connected directly to the closure C.

In the operation of the invention when it is desired to open the closure C a horizontal endwise pressure is imposed thereon, such as to effect longitudinal shifting of the bar 26, which in the arrangement here shown may be effected in either direction and which movement of the bar 26 imparts swinging movement to the links 24 and 28 relative to the bar 26 by reason of their pivotal connection with the upper bar 28 and the latters engagement with the links H and I1.

As the link 24 rocks, a corresponding movement is imparted to the toothed segment 22 and. is transmitted by the latter to the segment 2! so as to effect a corresponding rocking movement of the latter and of the link H but in a direction opposite that of the link 24. This movement of the links 24 and I! causes the bar 20 to move downwardly and longitudinally and also efiects rocking of the links l6 and 28 in opposite directions with the link It extending parallel with the link I1, and the link 28 extending parallel with the link 24.

An important feature of the invention resides in the fact that by reason of the interconnection between the segments 2| and 22 downward pull on the links 24 and 28 when the latter are inclined from the vertical, tending to cause the links to move to a horizontal position, is neutralized by this downward pull exerting through the segments an upward thrust on the link H such as to counteract the load on the links 24 and 28, thereby establishing a balance whereby the closure will remain at rest at any position in the limit of the path of travel permitted by the link and segment arrangement.

This balance is effective throughout the length of travel of the closure and accordingly the amount of work required to move the closure from either its open or closed position, or in either direction from an intermediate position,

will be the same and there will be no tendency for the closure to run free under momentum, thus reducing to a minimum any possibility of the closure slamming against any stop that may be provided therefor after it has been freed of the opening or closing pressure imposed thereon.

By thus mounting the closure its movement will be silent and will be characterized by a gliding motion and such movement may be effected 5 without the aid of any track or guide other than the guiding action afforded by the link structure D.

Manifestly the closure 0 may be of any suitable construction and may comprise a door or a win- 10 dow of any desired fabrication. The invention, however, lends itself particularly to the mounting of windows in small dwellings where the wall thickness is such as to inhibit the mounting of the ordinary sliding sash between wall studdings, since by the arrangement here shown the closure C may comprise a sheet of glass suspended directly from bar 26 and accordingly does not necessarily require a sash frame.

Furthermore by the link arrangement here shown but little space is required above the support A for the member D.

However, it will be understood that the invention is applicable to various uses such for example as garage doors, elevator doors, railway 2 car doors and various other closures of the type which are moved edgewise in and out of their closed position.

While I have shown and described a specific embodiment of my invention I do not limit my- 30 self to the exact details -of construction and arrangement shown but may employ such changes and modifications as come within the meaning and scope of the appended claims.
